Secrets Codes of i Phone and Some important settings for iPhone 4s

How to display the hidden settings of iPhone handsets?

Today's tip will help you to play with your iPhone mobile phone's using secrets codes. These secret codes will work on most of the Apple mobile handsets. You can display the hidden information of Apple handsets and troubleshoot the routine problems with the help of these codes.

Follow the list of latest Apple codes list:

         Code      -        Action

1.    *#06#  - To display the IMEI Number of the mobile

2.    *225#  - Use to display the balance detail of postpaid number

3.    *#43#  - Use to verify if call waiting is enabled

4.    *#61#  - Verify the number for unanswered calls

5.    *#62#  - Verify the number for call forwarding if no service is available.

6.    *#67#  - Verify the number for call forwarding if phone is busy

7.    *#646# - Use to display the minute detail of postpaid number

8.    *777#  - Use to display the balance detail of prepaid number

9.    *3001#12345#* -  Display the iphone inner settings

10.                      *#33#  -  To verify whether barring is enabled or disabled for outgoing

11.                      *#21# -  To display the settings for your call forwarding 

Tips 7 Settings for iPhone 4 and 4s:

1.  If you are going to forward your number, do so before you change any other settings (Settings->Phone->Call Forwarding->Turn ON->Enter number to which you want calls forwarded)

2. Disable 3G (Settings->General->Network->Cellular Data->OFF). Also check your Data Roaming; it should be off by default, but for some reason if it is on, turn it off here as well

3. Make sure WiFi is enabled (Settings->WiFi->WiFi->ON)

4. Turn of automatic pushing of email (Settings->Mail, Contacts, Calendars->Fetch New Data-Push->OFF and set Fetch to Manually)

5. Put the phone in airplane mode (Settings->Airplane Mode->ON)

6. If you wish to reset the usage counter to zero in order to monitor it throughout the trip and ensure usage remains at zero, go to Settings->General->Usage->Cellular Usage->Reset Statistics


NOTE: In my 4s I do not turn off Location Services and Notifications, as they both work over wifi as well as a cellular network. Disabling 3G and putting the phone in Airplane Mode ensures that they will use only the wifi network and not rack up expensive roaming charges.When I arrive in an international destination, I simply log into an available WiFi network and Voila! I have access to the Internet, email, Twitter, and can even make international phone calls with the iPhone Skype app without incurring cellular charges. When you return to the U.S., simply reverse the process, although you may choose not to reinstate the International Roaming and International Long Distance feature.
